Orthotic solutions for children with hypotonia

New research underscores years of positive clinical results. When it comes to orthotic management of pediatric patients with hypotonia, the medical literature is only beginning to document the effectiveness that clinicians have been … READ MORE

Gait: The cornerstone of intervention

Quantifying the effects of hypotonia starts in the clinic. Effective management of children with hypotonia requires an understanding of how the condition affects gait. Clinicians typically rely on their professional experience when … READ MORE

Ankle foot orthosis, AFO

The strength and stability of a person’s body is of paramount concern for individuals with Cerebral Palsy; the more stable a body is, the better a person can ambulate and complete tasks both big and small. Orthotic devices worn on … READ MORE

Orthotic Management of CMT, Charcot-Marie-Tooth

Ankle foot orthoses, AFOs, can help compensate for muscle weakness and accommodate related structural deformities in patients with Charcot-Marie-Tooth disease, but practitioners are constantly looking for ways to improve suboptimal … READ MORE
